Dec 11 #1 - Tetrahedra, Truels and Triangular Children

The first episode of my podcast is now out. You can listen to it on its own website straight away and over the next few days it will be appearing on all of the major podcast apps (it is already up in a few). Each one has a manual review process so there's nothing we can do but wait. This will be a fortnightly podcast dealing with mathematics, puzzles, numbers and games.
